Felipe Massa will use a brand new engine at the Singapore Grand Prix, in the knowledge that a 10-place penalty will have no effect on him as he will start from the back of the grid.

It will be Massa's ninth engine of the season, breaking the eight engine limit imposed by the FIA. A gearbox issue was to blame for Massa's qualifying problems, but he said he would still take the opportunity to use a fresh engine.

"I had a problem with the gearbox which seized unexpectedly, without giving any warning and so I had to stop out on the track: now we have to understand exactly what happened," he explained. "We will change the engine as a precaution, also taking into account the fact I am last on the grid."

Massa said he would have to rely on a bit of luck to help him move through the field on Sunday.

"I'm expecting to have a very complicated race, especially as we are at a track where overtaking is very difficult, but it's true that anything can always happen: rain, safety car, who knows! I am very disappointed of course because today we had a very competitive car, as Fernando proved."
